A murine model system was established to study immune responses to the Pnu-Imune vaccine, which is made up of 23 different pneumococcal capsular polysaccharides. In this animal model, antibody-forming cell responses to 21 of 23 individual polysaccharides in the vaccine were detected. The Pnu-Imune vaccine elicited good antibody responses from the spleens and mesenteric lymph nodes (MLN) of young mice, whereas a variety of other peripheral lymph nodes were unresponsive. The immunoglobulin M plaque-forming cell (PFC) response in the spleen to the Pnu-Imune vaccine (given intraperitoneally or subcutaneously) decreased dramatically with increasing age. However, the spleen and MLN differed in …

B lymphocytes from the pulmonary lymphoid tissues were stimulated with a variety of thymus-independent (TI) antigens by intratracheal (i.t.) immunization. Immune responses in the lungs and hilar lymph nodes (HLN), which are part of the localized lymphoid tissue, as well as in the spleen, the systemic lymphoid organ, were studied. Thus, primary i.t. immunization of mice with the TI-1 antigen trinitrophenyl-lipopolysaccharide (TNP-LPS) elicited both antigen-specific and polyclonal plaque-forming cell responses from HLN, lung, and splenic B lymphocytes. These responses appeared as early as 3 days after immunization and declined by day 7. Similar immunization with another TI-1 antigen, TNP-Brucella …
